Hello! Sometimes something strange happening on opnsesne. WAN goes to defunct state. As i see - main problem is that The command '/sbin/dhclient -c '/var/etc/dhclient_wan.conf' -p '/var/run/dhclient.re1.pid' 're1'' returned exit code '1', the output was 'dhclient already running, pid: 71216. exiting.'

There might be a race involved, between:

core/src/etc/inc/interfaces.inc

Line 3242 in c4bc519

killbypid("/var/run/dhclient.{$wanif}.pid", 'TERM', true);

and

core/src/etc/inc/interfaces.inc

Lines 3311 to 3315 in c4bc519

mwexecf('/sbin/dhclient -c %s -p %s %s', array(
"/var/etc/dhclient_{$interface}.conf",
"/var/run/dhclient.{$wanif}.pid",
$wanif
));

In the same function... if dhclient does not respond to SIGTERM it is likely stuck in the system forever.

If you can, please re-evaluate on 20.1 as 19.7 is no longer maintained.

I'm running a newer version and still having this issue as well:
OPNsense 20.7.1-amd64
FreeBSD 12.1-RELEASE-p8-HBSD
OpenSSL 1.1.1g 21 Apr 2020

My WAN connection will work fine for days with a DHCP renewal every 900 seconds from my ISP (Frontier FIOS). However, all of a sudden the WAN stops working and I see the exact same series of events seen above.

Wanted to add, after digging in more and troubleshooting I do not believe my issue on 20.7.1 was related to this old one so this may be better now. Mine appeared to be related to the way my ISP handled DHCP renew requests going to the gateway and seems to be fixed so far based on what I did here: https://forum.opnsense.org/index.php?topic=19143.0
